The red soundproof glass room in Big Walk turns one of the game’s most important mechanics—communication—into the puzzle itself. Shortly after starting the challenge, a glass barrier separates your group and prevents players on opposite sides from hearing each other normally.
To escape, you’ll need to uncover a hidden button, unlock the symbol board, and communicate the correct sequence of symbols through the glass. Completing the puzzle rewards you with a gourd needed for the Green Tower.
Here’s the complete solution.
Where to Find the Red Soundproof Glass Room
The red room puzzle is located south of the Green Tower.
If you’ve already found the puzzle involving the blue monitors mounted on poles, the red room is located just across from it. This makes the two puzzles convenient to complete during the same trip through the Green Tower area.
Look for the distinctive red house-like structure and head inside to begin.
How to Start the Red Room Puzzle
Inside the building, you’ll immediately notice a symbol board locked behind a cage.
The setup should look familiar if you’ve already completed the symbol puzzle used to open the Red Bridge earlier in Big Walk.
Before you can interact with the board, however, your team needs to activate two buttons.
There is one button at each of two opposite corners of the room. Have players press both buttons to activate the puzzle.
Doing so accomplishes two things: the gourd is released, but a large pane of soundproof glass also appears and separates the players.
You now need to solve the remaining puzzle while divided between the two sides.
How to Unlock the Symbol Board
The first objective after the glass appears is opening the cage surrounding the symbol board.
A hidden button is located behind a wooden beam on either the left or right side of the room. Its exact side can vary, but the player trapped alongside the symbol board should be able to see where it is.
The problem is that the button needs to be communicated to the teammate on the opposite side.
Since normal proximity voice chat won’t pass through the soundproof glass, the player who can see the hidden button needs to indicate its position another way.
Once the teammate presses the correct hidden button, two things happen:
- The cage surrounding the symbol board opens.
- A terminal appears on the opposite side of the room.
The terminal displays the sequence of symbols that must be recreated on the board.
How to Communicate Through the Soundproof Glass
This is the main challenge of the puzzle.
One player can access the symbol board, while the other can see the correct sequence on the terminal. Because the glass blocks normal communication, your team needs to find another way to exchange information.
There are two reliable methods.
Use Walkie-Talkies
Walkie-talkies are the easiest solution if your group has them.
The soundproof glass prevents normal proximity chat, but walkie-talkies allow players to communicate across the barrier.
The player viewing the terminal can simply describe the symbols and their correct order to the teammate standing at the board.
From there, the other player can arrange the pieces accordingly.
Communicate With Gestures
You can still solve the puzzle without walkie-talkies.
The player beside the symbol board should pick up individual symbol pieces and hold them up so the teammate on the terminal side can see them through the glass.
Use E and Q on keyboard or LT/L2 and RT/R2 on controller to manipulate and display the pieces.
The player who can see the terminal can then respond using character movements. A simple system works best: nod for the correct symbol and shake your head for an incorrect one.
Repeat the process until you’ve identified every symbol and placed them in the correct sequence.
It’s slower than using walkie-talkies, but it allows the puzzle to be completed using only visual communication.
How to Escape the Red Soundproof Glass Room
Once you believe the symbol sequence is correct, check the board carefully before submitting your answer.
Then:
- Make sure every symbol matches the sequence displayed on the terminal.
- Check that they’re arranged in the correct order.
- Press the button underneath the black screen.
- Wait for the puzzle to verify your solution.
If you’ve entered the correct sequence, the soundproof glass barrier will disappear and your teammates will be reunited.
You can then pick up the released gourd and leave the building.
If the barrier remains in place, the symbol sequence is incorrect. Check the terminal again and repeat the communication process rather than randomly rearranging the pieces.
Take the Gourd to the Green Tower
Completing the red soundproof room isn’t the end of the overall Green Tower objective.
The gourd is one of the items needed for Green Tower progression, so make sure someone actually carries it out of the puzzle area.
From there, take it back toward the Green Tower alongside the other required puzzle items you’ve collected.
For groups tackling several nearby challenges at once, it’s worth completing the blue monitor counting puzzle across from the red room during the same trip. Both provide items that contribute toward Green Tower progression.
Fastest Way to Solve the Soundproof Room
The puzzle becomes considerably easier if your team prepares before pressing the two starting buttons.
If possible, equip walkie-talkies beforehand. This effectively removes the puzzle’s biggest communication obstacle, as the player viewing the terminal can directly tell the other player which symbols to use.
Without walkie-talkies, agree on basic visual signals before entering. For example, use nodding for “yes” and head shaking for “no.” Once the glass appears, hold each symbol against it and let the terminal player confirm whether it’s correct.
The complete solution can therefore be summarized as:
Press both starting buttons → Find and press the hidden button → Unlock the symbol board → Read the sequence from the terminal → Communicate the symbols through the glass → Arrange them correctly → Submit the answer → Collect the gourd.
Once the sequence is correct, the glass disappears and you’ll have another item ready to take back to the Green Tower.
